Sculptures cast shadows from the fourth dimension
A mathematician would know better. In fact, the sculptures are an artistic interpretation of a 4D shape called the dodecacontachoron, or the 120-cell. That's 120 dodecahedra - a 3D shape with twelve pentagon faces - fitted together in intertwining rings.

In geometry, a Johnson solid is a strictly convex polyhedron, each face of which is a regular polygon, but which is not uniform, i.e., not a Platonic solid, Archimedean solid, prism or antiprism. There is no requirement that each face must be the same polygon, or that the same polygons join around each vertex. An example of a Johnson solid is the square-based pyramid with equilateral sides (J1); it has 1 square face and 4 triangular faces.
